Heinkel He-277 airplane model

An attempt by Heinkel to rectify the problems of the He 177 by mounting four single engines in place of the dual coupled engines, the He 277 was originally met with indifference by Goering. Heinkel was actually banned from developing this aircraft and secretly proceeded by designating it the He 177B. During a meeting with Hitler, Heinkel mentioned the aircraft as a solution to a specification Hitler was making for a long range bomber. Hitler ordered the type into production, at which point it reclaimed it's legitimate name of He 277. Numerous prototypes were built but on July 3, 1944 production was halted as the German aviation industry focused on fighter production to stem the constant allied bombing campaign.
